There are 19 species of woodcreeper at Cristalino, all subtle variations on the theme of reddish-brown with varying amounts of streaking and slightly different bills. They are, therefore, a nightmare to the uninitiated, especially as some of the local subspecies look very different to the nominate forms pictured in the field guides! This is the Dusky-billed (eytoni) subspecies of Buff-throated Woodcreeper, the commonest woodcreeper on the reserve.
